Method
 

step1:
  1. In a large mixing bowl, sift the powdered sugar to remove lumps. Add meringue powder. Whisk to combine.
step2:
  1. Add water, lemon extract, and light corn syrup to the dry mixture.
step3:
  1. Using a mixer with a whisk attachment, beat on low speed for 30 seconds until combined.
step4:
  1. Increase to medium speed and beat for 5–7 minutes until the icing becomes thick, glossy, and forms stiff peaks.
step5:
  1. Add white food coloring for brightness, then divide icing into bowls for custom colors. Add desired food coloring slowly — a little goes a long way.
step6:
  1. Adjust consistency:
  2. Thick icing (outlining): Should hold a firm peak.
  3. Medium icing (details): Flows slightly but holds shape.
  4. Thin icing (flooding): Add water 1/2 tsp at a time until it settles within 10–12 seconds.
step7:
  1. Cover bowls with plastic wrap touching the surface to prevent crusting, or transfer to airtight containers until ready to use.

❓ 10 FAQs
1. Why use corn syrup?
It gives the icing a smooth, shiny finish.
2. Can I make this without lemon extract?
Yes, use vanilla or almond extract.
3. Why add white food coloring?
It brightens the icing and creates a clean base for colored icings.
4. What’s the best way to thin icing?
Add water very slowly — 1/4 to 1/2 teaspoon at a time.
5. Why does royal icing get bubbles?
Beating too fast or too long adds air — let icing rest before piping.
6. How long does icing take to dry?
6–8 hours for full drying; overnight is best.
7. Can I color royal icing?
Yes! Gel colors work best because they don’t thin the icing.
8. Why is my icing separating?
Not mixed enough — re-whip for 30 seconds.
9. Can I freeze decorated cookies?
Yes — freeze in layers separated by parchment paper.
10. Why did my icing dry dull?
Too much humidity — use a fan or dehumidifier while drying.
